Abstract (en)
[origin: US4681998A] A method of welding studs inclusive of a bolt or the like to an underwater structure or a land structure in the rain or for mounting anticorrosive members, wherein the tip of the stud held by the welding gun is enclosed by a resilient, heat-resisting water sealing member and a gas generating agent is applied to the tip of the stud. The water sealing member is brought in contact with a base metal and an arc is generated by a current across the stud and the base metal so that the arc heat causes gas to be generated from the gas generating agent to force any water around the stud tip out of the water sealing member under a gas pressure, and then the stud is welded to the base metal in the absence of water.
